The year of 2012 has reached a top level when it comes to emissions of carbon dioxide from fossil fuels and cement production. The global level of pollution has risen last year 2.2 percent over 2011 mostly because of an increase in coal-burning China, scientists said on Tuesday.
Around 35 billion tones of CO2 were produced in 2012, 58 percent more compared to 1990, the benchmark year for calculating greenhouse-gas levels, according to the annual analysis by an international group called the Global Carbon Project.
“Based on estimates of economic activity in 2013, emissions are set to rise 2.1 percent in 2013 to reach 36 billion tonnes of CO2,” it said in a report according to the international press.
China, the world’s number one carbon emitter, accounted for 70 percent of the global increase in 2012, the report said. Emissions from China grew 5.9 percent in 2012, lower than the average of 7.9 percent per year over the last 10 years.
Japan had also a significant CO2 increase of 6.9 percent, followed by Germany (+1.8 percent). In the United States, the world’s number two emitter, CO2 emissions fell by 3.7 percent in 2012.
Emissions by the European Union fell by 1.3 percent, but emissions from coal grew 3.0 percent.
Carbon dioxide is the principal greenhouse gas, and fossil fuels – coal, oil and gas – along with cement production account for nearly all the man-made emissions.
The study involved 49 authors from 10 countries.
